Key stretching?

The correct answer is B.
Key stretching is the process used to take a key that might be a bit weak and make it stronger.
Blowfish is an encryption system.
I would go for B, but I understand why they may have preferred A as the correct answer. Bcrypt is a hash, designed to be much slower than other hashes like MD5 and SHA and slow down hackers creating rainbow table attacks. Bcrypt is based in Blowfish cipher.
